Gallbladder disease and gallbladder cancer among American Indians in tricultural New Mexico

Abstract
Previous studies have reported high rates of gallbladder disease and gallbladder cancer among all American Indians. Data from the New Mexico Tumor Registry confirm these findings, specifically showing high rates for New Mexico's American Indians, as well as for the state's Spanish population. This review explores several risk factors, including parity, obesity, age, cholesterol level, and genetic factors. From the available evidence, genetic factors appear to be the most important, with parity a contributing factor. Cancer 42:2472–2477, 1978.
